Pistas fósiles en la «Serie de Carrascalejo». Implicaciones cronoestratigráficas

Abstract

Trace fossils (Cruziana and Rusophycus) are described for the first time in the Carrascalejo beds. The stratigraphy of this unit is also modified; the conglomeratic basal beds are included in the underlying Precambrian series. An Upper Cambrian-Tremadocian age for the Carrascalejo beds is based both on trace fossils and on the regional stratigraphy
